Description

Technical Field

[0001] This utility model relates to the field of glass surface inspection technology, specifically to a device that can improve the accuracy of glass surface inspection. Background Technology

[0002] The overflow-pull-down method for BOD (Block Oven Deposition) equipment in the flat glass manufacturing industry is applied in the packaging area of ​​the semi-finished product process. It involves rapidly reducing the temperature of the glass sheet under normal production line conditions, thereby further improving the accuracy of defect detection on the glass sheet surface. The overflow-pull-down method is one of the main methods in flat glass production. Molten glass overflows from both sides of a refractory chute and converges at the lower tip of the chute, forming a glass sheet, which is then pulled by a traction mechanism to form the final glass sheet. Because the glass surface does not come into contact with any other material, this method can produce thin glass sheets with good surface smoothness, flatness, and uniform thickness.

[0003] The specification of a planar testing device and method for improving the surface properties of glass (publication number CN113916161A) mentions that "the testing component is used to perform testing of the glass; the clamping component is used to clamp the glass; the testing component includes a lateral moving unit mounted on the operating table, and a testing unit mounted on the lateral moving unit; the testing unit includes a testing frame, a light emitter fixedly mounted on the testing frame, and a light receiving part rotatably connected to the testing frame." However, the existing technology cannot reduce the temperature of the glass plate, which leads to excessively high plate temperature causing bulging during packaging and accidents such as broken glass plates during packaging. It is not safe, convenient, or practical. Utility Model Content

[0007] Furthermore, the lower part of the mounting bracket is provided with support legs, and the lower end of the support legs is fixed to the base plate, and the upper surface of the base plate is provided with multiple sets of U-shaped tube seats.
